You are targeting CEO/CTOs. You need to have conversations with them. It'll be impossible to reach those at large companies, but maybe you can find smaller companies and get their feedback. ALL the other things are wasted effort until you have that feedback. And, this is a ton of work, you'll need to improve your skills in reaching out to people, selling them on why even having a meeting is good for them, then sell them in the meeting, then figure out a way to get past the fear of closing them in that meeting. Those are transformative skills to have. You'll probably need a coach to get you past all your blind spots. Its worth it to do that. Or, at least get yourself into a mentorship group with real concrete goals and people that will ask hard questions of you and hold you to your answers.
